"Known in the region as somewhat of a 'local celebrity,' Salvini struck up a bond with the artist over the course of his visits and as a sign of his gratitude Lowry drew these works for him on separate occasions."

The doodles were among a number of paintings by LS Lowry at the Bonhams Modern British and Irish Sale.

The current world record for a Lowry work is held by his famous oil painting The Football Match, which sold for more than £5.5 million in 2011.
